Hello,

just a side question related to this topic: Is there anyone working on a newer version of the ec_e1000e driver or did anyone patch the Intel Igb driver which is used for more recent dual-port network adapter?

Best regards,
Christoph

If you have a look in the “devices/e1000e” directory you can see the kernel versions that are currently supported.  You can either downgrade your kernel to one of the matching versions, try to generate a patched driver for your current kernel (by following the existing sources), or use the generic driver instead.  Note however that using the generic driver means you will probably need to use a slower realtime cycle rate as it will typically have more jitter.

Thank you for the response!
I am currently trying to install EtherCAT Master and I am running into a problem. When trying to configure and build using the command:

./configure --disable-8139too --enable-e1000e
I get the error:

checking for kernel for e1000e driver... configure: error: kernel 4.2 not available for e1000e driver!
Do I need to use a different kernel, or is there a work around to this problem?

Hi all,

New user here. I discovered EtherLab while trying to come up with a
solution for streaming data from a force sensor with EtherCAT connection to
my Linux PC. This PC is running Ubuntu 14.04 with kernel 4.2 and has a
e1000e driver. My ultimate goal is to send the force data to a C++ code in
real time in order to control a KUKA 7-DoF robot arm.

I'm still confused about the EtherLab software components and was hoping
someone could help guide me. If I just want to stream the data to the PC
and maybe visualize it using the terminal, do I need any of the software
components beyond EtherCAT Master?

Thanks everyone,
Justin

P.S. Any additional advice/suggestions that you may have for me would also
be greatly appreciated.

Hallo Justin,

indeed you need an application. The EtherCAT-Master is more or less like
a Ethernet driver which gives you the ability to access the network
stack but has no application functionality (my apologies to the
programmers of EtherCAT and Ethernet for simplification here). Look at
the examples which come with the EtherCAT Master.
